Peripheral Nerve Injury

Novel Biodegradable Regeneration-Type Neural Interfaces for High-Resolution Stimulation and Recording from Peripheral Nerves

We aim to develop novel, high site-count microelectrodes that are optimized for electrically stimulating and recording from regenerated peripheral nerves. These devices will facilitate the creation of next-generation neuroprosthetic systems for restoring function to upper- and lower-limb amputees.

Chemical structure of desaminotyrosyl-tyrosine alkyl esters derived polycabonate, abbreviated ‘poly(DTR carbonate)’. The carboxylic acid terminal group is protected by an alkyl ester which can be regarded as a pendent chain. The structure of the alkyl esters is indicated by the following nomenclature convention: DT, desaminotyrosyl-tyrosine ester; DTE, desaminotyrosyl-tyrosine ethyl ester; DTB, desaminotyrosyl-tyrosine butyl ester; DTH, desaminotyrosyl-tyrosine hexyl ester; DTO, desaminotyrosyl-tyrosine octyl ester; DTD, desaminotyrosyl tyrosine dodecyl ester. These particular monomers are most commonly used in the synthesis of tyrosine-derived polymers (Right) Porous scaffold fabricated from poly (DTE carbonate) with a bimodal distribution of macro- and micro-pores. Macropores (212–425 mm) are the impressions of the salts, the micropores (about 1 to 10 mm) are caused by the formation of frozen solvent crystals during cooling (Bourke & Kohn, 2003).


Intrafascicular Electrode & Peripheral Nerve Signal

1. We aim to study long-term recording of nerve signal by modified intrafascicular electrodes in rabbits. Methods for long-term recording of peripheral nerve activity via intrafascicular electrodes have not been optimized. Intrafascicular electrodes with a spring-like structure demonstrated superior potential for long-term electrophysiologic monitoring over straight electrodes. ‌

2. The residual motor pathways after amputation have not been fully elucidated. We sampled potentials from peripheral nerve stumps with intrafascicular electrodes to study residual motor transmission and explore the feasibility of nerve signal-controlled artificial limbs. The long-term amputee was able to generate motor neuron activity related to phantom limb movement. Intrafascicular electrodes can be used to monitor residual motor nerve activity in the stump and the amplitude may predict successful control of artificial limbs.
